Normal Map
Works out a tangent-space normal map by treating the picture's brightness as a height field. The output switch can also show the raw normals, the source height, or the steepness of the slope.
What it does
Normal Map is an image effect: it changes the picture that flows through it. It takes picture in and gives picture out.
Try it
Turn a Noise or Texture into a bump map for a Material's surface.
